The X Drive Boards deliver the Color drive signals to the Vertical Grids via TCPs.
The 50PQ30 has a Left, Center and a Right X-Drive board.
The Center X-Board has 6 connectors to a TCPs.
The Left and Right have 5 connections to TCPs.
Each TCP has 2 internal buffers.
Each buffer controls 128 vertical grids lines (256 per/TCP).
Generally speaking, there isn't many active components on the X-Drive Boards.
So they are not very prone to failure.
In this section the X-Drive will be discussed and information given allowing the
service technician to determine if a failure has occurred in the X-Drive section.
X-BOARDS CONTROL THE VERTICAL ELECTRODES WHICH DETERMINE THE HORIZONTAL PIXEL COUNT.
TOTAL VERTICAL ELECTRODES 4096. TOTAL HORIZONTAL PIXELS 1365.
Total Buffer Count = 36
(TCPs = 16 @ 2 buffers per/TCP)
Total Output Pins = 4096
(128 per buffer X 36 total)
Total Pixels (Horizontal) 1365
(4096 / 3) Three cells per pixel (Red, Green and Blue)
